- FINIsn-REMov'EQ To all whom it may concern: v

Be it known that I, CARLE'ION ELLIs, a citizen of the United States, and resident of llarehnion t, in the county of VVestchester and State of New York, have invented certain new and useful Ini rovements in Finish-Removers, of which t 1e 'following'is a specifica-' tron.

-This invention relates to paint and varnish removers comprising organic finish solvents carrying an i-norga'nic'compound in a state or condition whereby retardation of evaporation of the finish solvent is attained, and when-desecured.

Many, of the halogen compounds of antimony and some of these of-arsenic, tin, lead and the like dissolve in volatile organic sol-' vents, and afford slowly evaporating compositions of some degree of consistencyv which have valuable paint and varnish removing properties. Among such compounds may be mentioned the chlorids of antimony, particularly the triehlon'd or butter of antim'ony, which is soluble in volatile solvents such as aleolwl; antimonyl chlorid, a compound little soluble in alcohol, ether and acetone, but somewhat soluble in chlorids of carbon, earox mhlorid' of the formula ShOCl and var1- ous other oxychlorids of both antimonic and solubility in these and similar .organic volatile solvents; s nnlarly with the bromlds Spine, sulfoehloruls are also ons double salts may be formed from these bodies giving rise to compounds'of a more or iessneid, or even neutral nature. Calcium and magnesium chlorid areexamples of salts. in-ignjrblo ohlorming, double salts with the above "mentioned compounds. Ammonia (o1ubinmililfller' freely with these antimon eoninonnds giving useful bodies. Sulfur 13 but insoluble in illi' llUl.

The latter are essentially volatile and comprise such bodies as benzol and its Specification of Letters Patent. Application filed July 28.1907. Serial Fo. 385.177.

tetrachlorid acet form, chloride of. enzol and other aromatic bodies, variousalcohols as wood, grain, denatured, amyl alcohol and the like, also acetone, .methyl ethyl ketone and analogous bodies, .wood turpentine,- oil of acetone,etc. 'Alcoholic chlorids, acetic acid, and similar volatile solvents have a desirable blending action. A removi ngf-co1 nposition may be re ared by dissolving pure l'antirnonyl c lori A-suitahlecomposition may be lreparedi by warming fo'in parts of denatured alcohol saturated] with ammonia as with one 'part ofbutte'rof antimony. alcohol or acetone, one half part of concentrated ammonium hydro-oxid and one part of butterof antimony, mixed in the order mentioned area a remover effective on sandarac varnish. Butter of antimony has the pro erty of rendering alcoholic bodies immisci le with benzol'and similar hydrocarbons,- thus affording the 'me ns-for the preparation of emulsions of enzol and 11 01101., By suitably thickening the benzol permanent emulsions may be prepared. 'A'

cunous property of butter offalntimony is its action on waste cellulose sulfite liquor; A liquor of 30 Baum is insoluble in wood alcohol, etc., but the addition of a small amount of butter of antimony brings the liquo'r into solution. A- mixture by volume of five parts of. wood alcohol, three parts of but ter of'anti'mony and two parts of sulfite liquor has the power ofdissolving consider-- so able benzol. preparation of alcoholic removers containing butter ofantimony it is often desirable to have present from five .to ten per cent. of water as the oxyc'hlorinated dompound formed has con siderable evaporation retarding action. The consistency 1s 'varie'd'by increasing, or de creasing the amount of the'chlorid; also by varying the proportion of alcohol. Avery small quantity oi alcohol makes a stripping remover which softens th finish just sufliciently so that it may be removed in large films or sheets. 1 Y

For removin resin varnish from one half to one pound 0 the chlorid may be dissolved in one gallon of lzenzol, without the addition of alcohol.
